How it works
Mode of action
Adult parasitic wasps emerge from the mummies and females lay their eggs into aphids. The next generation of parasitic wasps develop inside the aphid, which converts into a leathery mummy. The adult parasitic wasp emerges through a hole at the rear of the mummy. The first mummies are noticed in the crop around 10-14 days after the first introduction.
Parasitized aphids turn into a brown mummy.

Directions for use
- Spread the material on rock wool slabs or in Diboxes
- Make sure the material remains dry and is not moved from its introduction site for at least a few days
The dosage of Ervipar depends on climate, crop and aphid density and should always be adjusted to the particular situation. Start introduction preventively soon after planting of the crop. Introduction rates typically range from 0.25-2 per m2/release. Releases should be repeated weekly during the period when aphid infestation is expected. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
